Abstract: A sealing sleeve for inserting into a piping system in order to seal a leak, having a steel sheet, which is annularly bent together and having at least one locking device in the form of a slot which is arranged in the steel strip in the circumferential direction and which has at least one row of teeth. The locking device also having at least one detent member, which is suitable for engaging in at least one row of teeth. The detent member has at least one guide element, at least one detent element and at least one tensioning element, which is arranged between one guide element and one detent element and is designed in such a way that the tensioning force between the guide element and the detent element can be varied and thus the detent effect of the detent member can be controlled.

Abstract: An arrangement for producing structured substrates is provided, which includes a device for applying layer systems including a device for applying liquid materials to rotating substrates, a housing, a rotating holder for the substrate to be coated, a feeder for liquid materials to be applied, and a collection device having multiple removal contraptions for liquid materials that do not remain on the substrate. The housing of the device is filled with an inert gas, in particular dried, molecular nitrogen, noble gas, or a mixture thereof. The additional receptacles and conduits of the arrangement for producing structured substrates are gas-tight and are designed such that an inert molecular nitrogen or noble gas atmosphere is created above the liquid contents thereof. The collection device has various collection zones in which different liquid materials can be selectively collected and selectively removed via the associated removal contraption.

Abstract: A system is provided that includes a fluid-tight tube, which for insertion can be introduced into the area of a gap to be sealed between two pipes of the pipeline system to be sealed. The tube is provided with a feed element for introducing a fluid, with whose aid the tube is filled and thereby increased in its volume. The feed element contains a valve, which facilitates the introduction of the fluid and at the same time prevents the outward flow via the feed element.
